: Specific impurity limits, such as iron content, are strictly defined for these methods.

: Often allows for the highest levels of impurities (up to 2.10% total) to accommodate the rapid cooling and manufacturing process. Key Alloy Examples and Properties

: Generally allows for higher iron content compared to sand casting. gost 2685-75 pdf

) of at least 147 MPa and a Brinell hardness of 45 MPa. It is primarily composed of aluminum with 4.5–6% Silicon and 2–3% Copper.

: Known for higher magnesium content (9.3–10%), this grade offers improved mechanical properties, which can be further enhanced by 15–20% if iron and silicon impurities are limited to 0.030%. : Specific impurity limits, such as iron content,

: Used for high-precision components.

The GOST 2685-75 standard covers aluminum alloys intended for the production of shaped castings. It classifies alloys based on their chemical composition and the specific casting method used, such as: ) of at least 147 MPa and a Brinell hardness of 45 MPa

Several well-known aluminum grades fall under this specification, each tailored for specific industrial needs:
